Hello
I saw a trend that, every ESP has taken hard work on antispam policy.
For example, from my test cases:
1. gmail totally can't be registered from PC, only mobile client (gmail,
outlook etc) can sign up a new username. they require mobile
verification in the process.
2. yahoo totally can't be registered without a mobile verification, and
each telephone number can be used once.
3. yandex is harder to sign up, it requires mobile verification, before
every message sending, they require you to input the auth code.
4. A new registered outlook email require you to input mobile number
once and once.
5. GMX/web.de stops auto-registration, every new registration they
require you to call their service telephone for manual verification.
6. yahoo.co.jp stops web registration, they require mobile verification,
and use a password-less solution for login. the first new messages
sending they require you to input Japanese auth code.
7. others including UKR, rambler, Netease have the silimiar rules.
Does this mean every country has taken the strictest antispam laws for
privacy protection today?
Thanks & Regards.
